Question

Find the value of Sec 60° + Cosec 30​

Answer 1

Answer:

The answer is 4

Step-by-step explanation:

         $\sec60^\circ+\cos ec 30^\circ$

       $=\dfrac{1}{\cos 60^\circ}+\dfrac{1}{\sin 30^\circ}\\\\=\dfrac{1}{\frac{1}{2}}+\dfrac{1}{\frac{1}{2}}\\\\=2+2+4$

• Since $\sec\theta\sec\theta=1,\cos ec\theta\sin\theta=1$ and $\sin 30^\circ=\frac{1}{2},\cos 60^\circ=\frac{1}{2}$
